Astrologer Richard Noelle first coined the term supermoon in 1979 with the following definition: "a new or full moon which occurs with the moon at or near (within 90% of) its closest approach to Earth in a given orbit (perigee)."

The difference between the different full moons throughout the year is not that big. In fact, the passage of the moon's disk into the Earth's shadow will result in one of the slightest eclipses of all, administering a mere touch of penumbral shadow (Earth shadow) at the southernmost part of the lunar limb at 12:11 a.m. EDT on Friday.

This is the point of greatest eclipse, where the penumbral magnitude will only reach 1.57 percent; the penumbral shadow will be in contact with the moon for only a little more than 33 minutes. 

It will thus be impossible to notice anything out of the ordinary concerning the moon's overall appearance. It will, in fact look like any other full moon 

So if we can't see it, why bother even including it in the listing of this year's eclipses? To quote the well-known Belgian eclipse calculator, Jean Meeus, the mention of such a slight and undistinguishable event such as this is done, "... only for reason of completeness; the statistics of eclipses would be incomplete without them."

They do not appear in different colors - just your average beautiful round full moon.

Below is a special full moon calendar for the year 2013, taken from Farmers Almanac. For those of you impatient to gaze upon the next Supermoon, it should be visible Sunday, June 23rd.
